with removable covers, and has more partlc-f ular reference to-a machine for beading and flanging the receptacle bodies.

In the manufacture of receptacles of this character it is essential that the lower edge of the receptacle be provided with a peripheral flange to which the bottom of the receptacle is secured by a double seaming or similar operation, and it is also desirable that a bead be produced a short distance from the top of the receptacle at a point in proximity to the lower edge of the cover when the cover is applied in position on, the.

receptacle.

One of the primary objects of my present invention is the provision of a machine which will automatically bead and flange these receptacle bodies rapidly and accurately without attention to or handling of the receptacle bodies by the operator.

Another object ofmy invention is to provide a machine of this character which will be simple in construction and strong and durable, and which will be capable of adjustment so that it will handle bodies of different diameters and heights.

While a machine embodying my invention is adapted to operate upon sheet metal bodies of various characters and sizes, and while these bodies are not generally, strictly speaking, called can bodies, in the sense that the word an is customarily used, nevertheless, for convenience I will hereafter refer to these bodies in this case as can bodies, using the word can generically to designate any sort of a cylinder body capable of being.

operated upon by my improved machine.

For the purpose of facilitating an understanding of my invention I have illustrated one preferred embodiment thereof on the ac companyhig drawings, from an inspection of which when considered in connection with the following description my invention and its mode of operation should be readily understood. Referring to the drawings,

Figure 1 is an elevation of a machine embodylng my invention looking toward the delivery end thereof;

Fig. 2 is a side elevation looking toward the left in Fig. 1, certain parts being broken away to more clearly illustrate certain'features;

Fig. 3 is a sectional view taken on the line 3- of Fig. 1;

Fig. 4: is an enlarged sectional view on the line 4-l= of Fig. 3;

Fig. 5 is a detail sectional view on the line 55 of Fig. 3;

Fig. (5 is a sectional view on the line 6-6 of Fig. 2; and

Fig. 7 is a fragmentary plan view, viewed from the line 7-7 of Fig. 2.

By reference to the drawings it will be observed that the machine comprises a body or.

frame construction, designated enerally by reference character 8, which is esigned and proportioned to accommodate and carry the various mechanisms to be hereinafter described. A shaft 9, hereinafter referred to as the cam shaft, is journaled in suitable bearings and extends transversely of the machine, one end of the shaft being equipped with a loosely mounted belt )ulley 11 adapted to be secured to the sha t at will by the manipulation of a clutch member 12 splined on the shaft and constructed to engage with a companion clutch member 13 carried by the pulley 11. The pulley 11 constitutes the drive pulley for the machine and power is applied to this pulley from any suitable source through an ordinary belt.

Above the shaft 9 there is mounted in suitable journal bearings 1- and 15 a chuck shaft 16 carrying at its inner end a chuck 17. This shaft also has fixed thereon between the bearings 14 and 15 a belt pulley 18 and a grooved collar 19, into the groove of which projects a pair of rollers or studs 21 carried by the bifurcated upper end of a lever 22 fulcrumed on the main frame at 23. A contractile spring 24 fixed at one end to the frame of the machine and at its other to an arm 25 projecting from thelever 22, normally urges the upper end of the lever outwardly into the position shown in Fig. 1,

but at periodic intervals the lever is swung so as to move its upper end inwardly by means of. a cam 26 mounted upon the shaft 9, the lower end of the lever 22 being equipped with a roller 27 riding upon the face of the cam 26.

Asimilar chuck shaft 28 is mounted in the bearings 29 and 31 in axial alinement with the shaft 16. This shaft carries at its inner end a chuck 32 opposed to the chuck 17 and is also equipped with a'belt pulley 33 and a grooved collar 311, and the shaft is reciprocated longitudinally by a lever 35, which is moved in one direction by a cam 36 mounted on the shaft 9 and in the other direction by a spring 37, all similar in construction and operation to the mechanism on the other side of the machine, which has been previously described. The cams 26 and 36 are so designed and mounted that the two shafts 16 and 28 will be moved synchronously to cause the chucks 17 and 32 to approach each other and recede away from each other at regular predetermined intervals. 1

Referring now to Fig. 2, it will be observed that the feeding or receiving end of the machine is provided with an inclined chute 38. This chute comprises two side members and a; bottom member of suitable construction, the side members being carried by blocks, 39 and 41, adjustably mounted in supporting guideways, 42 and 43' respectively, carried by a frame structure including a casting 44 which is vertically adjustable in a guidewa- 45 fixed to the main frame of the machine. The lateral adjustability of the side members of the chute enables the chute to be accommodated to can bodies of various heights or lengths, which are fed to the receiving end of the chute manually, or otherwise, and are permitted to roll down the chute to the lower end thereof, a number of can bodies being shown in dotted lines in Figs. 2 and 3 and indicated by reference character 46.

Near the lower end of the chute there is mounted a transferrer, which is designed to transfer the foremost can from the chute into position between the retracted chucks 17 and 32 and in substantially axial alinement with these chucks. This transferrer consists of a pair of members 47 having flat upper faces adapted when in lowered position to form a continuation of the bottom of the chute 38, the upper ends of these members being curved upwardly as indicated at 48 to serve as a stop or abutment for the foremost can-body, the rear ends of the members being provided with a downwardly extending arm or finger 49 which, as the transfer members are swung upwardly to transfer a can-body, serve to hold back the following can-bodies in the chute as shown in Fig. 3. Each of the. members 47 is mounted upon a block 51 by a'slot and bolt connection so as to be laterally adjustable toward and from each other to accommodate them to can-bodies of various lengths. The blocks 51 are mounted upon a pair of arms 52 pivoted at their rear ends upon a shaft 53 supported intermediate its ends in a block 54 mounted upon a bracket 55 carried by the machine frame, as best shown in Figs. 2, 3 and 6. A link 56 disposed between the arms 52 is bifurcated at its lower end to straddle the shaft 9 and carries at one side an anti-friction roller 57 which travels upon a cam 58 mounted upon the shaft 9, suitable contractile springs 59 being employed to maintain the roller 57 against the cam face. The upper end of the link 56 is adjustably connected to both of the arms 52 by means of a bolt 61 which extends through the link and through elongated slots 63 formed in the arms 52 so that by varying the position of the bolt in these slots the extent of movement of the arms, and thereby the travel of the transferrer members 47, at each revolution of the shaft 9 may be regulated and adjusted.

\Vhen the parts are in the position shown in Fig. 2 the foremost can-body will rest upon the transferrer members 47, and as the shaft 9 revolves into the position shown in Fig. 3 the transferrer members will he swung upwardly to carry the foremost canbody into position between the chucks 17 and 32. The fingers 49 during this movement prevent the succeeding can-bodies from rolling down the chute and the cams 26 and 36 are so timed that when the can-body has been alined with the chucks both chucks will be moved inwardly toward each other into the opposite ends of the can-body.

To assist in alining the can-body with the chucks I have provided a guide-member 64 which overlies the chute and prevents the can-bodies from becoming dis )laced, the rear end of this guide-member being provided with a resilient extension 65 which tends to hold the can-body down upon the transferrer members 17, as it is moved into position. A pair of check pieces or side plates 66 and 67 are carried upon angle members, 68 and 69 respectively, which are supported upon blocks 71 mounted for lateral adjustment in a guiding support 72 having a downward extension 73 which is vertically adjustable upon the rear face of the block 54. The blocks 71, carrying with them the angle pieces 68 and 69, upon which the side plates 66 and 67 are mounted. are capable of lateral adjustment to accommo date various lengths of cans, and are normally adjusted so that the can-bodies will enter between the side plates with only comparatively slight clearance. The side plates are also provided with openings through which the chucks 17 and 32 may be pro tltl jected into the can body, as shown in Fig. 4:. To'further assist in alining and positioning the can-body for the reception of the chucks, each side plate has mounted upon its inner face a roller 74 carried by a bar 75 which is adjustable upon the side plate by reason of an elongated slot in the side plate, through which the securing screw 80 projects. These rollers 74 serve as abutments against which the can-body is moved by the transferrer members, and upon rotation of the can-body by the chucks these rollers hold the body snugly against the chucks and prevent the ends of the body from becoming distorted.

It will be understood that the chucks are continuously rotated at an appropriate speed by means of belts which are trained over the pulleys 18 and 33, and when a can-body has been positioned in alinement with the chucks they are moved inwardly into the body as shown in Fig. 4, whereupon the 'body is I8- volved with the chucks. The chuck 32 is provided with an inclined face 76 and chuck 17 is provided with a groove 7 7 and a bead 78, all as shown in Fig. 4. Furthermore, the chuck 17 is provided outside the bead 78 with; a cylindrical portion 79 so that the upper end of the can body, when conformed to this portion 79, is cylindrical so as to receive the cover while the portion of the body below the bead is generally tapered toward the bottom as is customary in pails of this character, and as shown in Fig. 4. While the can is revolving with the chucks a flanging roller 81 and a beading roller 82 are forced against the outer face of the can into cooperative relation with the chucks to produce a flange at the lower end of the canbody and a bead near the upper end, as will be evident from Fig. 4. It will be under stood'that the roller 81 is provided with an inclined face 83 cooperating with the face 76 of the chuck 32 while the roller 82 is provided with a bead 84 and a groove 85 00- operating with the groove and bead respec tively on the chuck 17. The rollers 81 and 82 are carried by blocks 86 which are laterally adjustable upon a crosshead 87, the blocks being secured thereto by bolts 88 passed through elongated slots 89 in the crosshead. This crosshead is pivotally mounted upon a shaft 91 carried by suitable bearings 92 formed on the main frame of the machine and is provided with a rearwardly extending arm 93 to which there is adjustably connected a link 94. The lower end of this link is bifurcated to straddle the shaft 9, as shown in Fig. 3, and upon one side of the link there is mounted an anti-friction roller 95 bearing upon the periphery of a cam 96 mounted upon the shaft 9, the roller being urged against the cam face by a contractile spring 97. The cam 96 is so timed that when the chucks have entered the can-body so that the body is rotating with the chucks, the crosshead will be swung on its shaft 91 to force the flanging and beading rollers, 81 and 82 respectively, against the can-body so that in conjunction with the chucks the required operations are simultaneously performed upon the body. After a suflicient number of revolutions of the body have oc curred to complete the operation, the beading and flanging rollers are withdrawn from the chucks and the chucks are then drawn apart, permitting the body to drop down upon the angle members 68 and 69 and roll to the lower ends of these members, where they are discharged from the machine into any suitable receptacle. Side plates 98 are preferably mounted upon the angle members 68 and 69 to insure the travel of the can-bodies to the lower end of the delivery chute and prevent any possibility of their being dropped into the machinery.

It should be obvious, from the foregoing, that the can-bodies fed into the receiving chute roll down to the transferrer by which they are transferred one at a time and accurately positioned between the chucks, whereupon the chucks are moved toward each other into the endsof the body, thus causing the body to revolve with the chucks. The abutment rollers 74: assist in alining the body with the chucks and also prevent distortion of the body while it is being revolved by the chucks. During the revolution of the body the heading and fianging rollers are forced into'coopcrative relation with the chucks'to produce the required bead and flange.

After the operation is complete the rollers are withdrawn and the chucks are retracted, thus permitting the beaded and flanged body to drop into the delivery chute and be discharged from the machine. In the meantime. the transferrer has returned to lowered position to receive the next succeeding canbody which is then positioned at the proper time between the chucks, whereupon the operation is repeated.

It is believed that my invention and its mode of operation should be understood from the foregoing without further description and it should be manifest that the structural details of the machine disclosed are capable of considerable modification and variation within the scope of the appended claims.
